I wanted to try out a new Lyman mold this morning.
And I grabbed a couple of ingots that were supposed to be made of the old tire wheel weights and solder.
There was not supposed to be any zinc weights in them.
Well, the crap melted at a very high temp---the dross turned blue---didn't want to flow out of the bottom pour nozzle---and the bullets were about 15 grains lighter than what lino out of that mold should be.
I have only ever used wheel weights [the old ones], linotype, and solder.
So this was a new experience.
Do you reckon that there was zinc in the ingots?
